Acomposite I-beam is 5 formed by the beam 6 and the nailing members i forenabling boards 8 and 9 to be secured by nails I 0 and H to thestructural composite I- beam formed by the beam 6 and the members I.

The serpentine shaped ribs are tapered laterally 10 at one or both endsl2 to a reasonably sharp edge at the point where the nail will enter theserpentine spaces or voids of the compound member so that any nail whendriven between the two elements of the compound member will be 5 guidedinto one of the serpentine shaped voids between the ribs and will benditseif along the course of the void and by so doing fasten itself andany collateral material through which it has previously passed, securelyto the compound metallic member. The parallel serpentine ribs cause anail to be successively bent in opposite directions and are so shapedthat it is'impossible for a nail, of any diameter less than the distancebetween two ribs, to pass along the void or space between the ribswithout being bent and thus fastening itself securely within the member.This enables the use of any type of nail of sufllcient length topenetrate the member and of a diameter equal to or less than thesmallest cross sectional dimension of the void. Nails of sufficientlength to extend beyond the nailing member may be used and after beingdriven into the nailing member the terminal i3 may be bent over andclinched against the inner edge of the flange or portion having theserpentine ribs, although this clinching or bending of the inner end ofthe fastening is not necessary for effective anchorage of the fastening,the free. end vof the fastening automatically bends following out theline of curvature. The serpentine grooves are adapted to cause theterminal l3 to curve laterally so that the end of the nail will not bedriven into material at the opposite side of the nailing member but willcurl up without penetrating the same.

The angle bar I is slightly curved at ll at the .juncture of its flangesso that when it is applied a to a structural member, as illustrated inFig. 6 of the drawings, a tapered entrance space l5 leading to the nailreceiving voids is formed. The 0 laterally tapered ends 12 of the ribs 3present a sharp edge to the ends of the nails entering the nailingmember so that it is impossible for the ends of the ribs to form anabutment and cause the nail to bend without entering a void as thebevelled face It of the tapered end will guide the end of a nail intothe serpentine space between it and the adjacent rib.

The ribs are of sufllcient thickness to enable the nails to be receivedwithin the spaces between the ribs and to lie wholly between said ribs.By this construction the internal forces created by a nail as it curvesitself along the void between two ribs, are contained wholly within thenailing member, or member having the ribs and do not a have 'a tendencyto separate the metallic nailing member from the structural member towhich it may be secured: The structural member to which the metallicnailing member is secured flts and in Fig. 5 of the; drawings theinvention is applied to a plain ba; or member is which is substantiallyflat wit e exception that its end edges 20 are preferabl .jdefiectedslightly to form a flaring entrance to; he serpentine spaces or voidsbetween the ribs when the bar or member i9 is applied to a structuralmember. In Fig. 7

of the drawings a member I 9 is shown applied to each of the bottomflanges 2! of a metallic I-beam 22, the upper portion thereof beingbroken away. The member having the serpentine ribs applied to one of itsflat faces may be of any structural form and may be combined with anystructural member having a flat face. This will enable collateralmaterial to be readily nailed to structural elements or members ofvarious forms. It will be understood that nails or other fasteningsmaybe driven into the voids or spaces between two metallic membersunited with the voids or spaces therebetween from either longitudinaledge of the compound metallic member as shown for instance in Fig. 8 ofthe drawings.

In all the forms of the invention heretofore described the ribspreferably terminate at their ends short of the longitudinal edges ofthe metallic member with which the ribs are formed. In Figs. 9 and 10 ofthe drawings is illustrated a. metallic channel member 23 provided withintermediate rows of circular bosses 24 which are flanked by marginalrows of circular bosses 25 and .26 which are staggered with relation toeach of the intermediate rows of bosses 24. The bosses which projectfrom the flat web portion of the channel member 23 present flat faces tofit against a structural member to form a compound structural member ina manner heretofore explained. Said bosses 24, 25, and 26 formserpentine or tortuous nail receiving voids or passages for bending andgripping nails in the manner heretofore explained. The rounded edges orsurfaces of the flanking sets of bosses 25 and 26 provide tapered orflaring entrances to the said voids or passages at each of the marginaledges of the metallic nailing member 23 to provide for entrance of anail or other fastening for serpentine formation or passage of thefastening as it passes through the respective spaces or voids betweenthe bosses 24, 25, and 26 as will be well understood. The bosses 25 and26 are arranged preferably'within the longitudinal edges of the metallicnailing member 23 and the curved outer portions of the edges of saidbosses 25 and 26 form guiding means between the members of a compoundstructural member to insure guidance of a nail or the like betweenadjacent bosses 25 and 26 as in the case of the tapered ends of theaforesaid ribs.

In Figs. 11 and 12 of the drawings is illustrated another modificationof the invention in which the metallic nailing structural member is inthe form of an angle bar 21 provided on one of its flanges withalternately arranged transverse ribs 28 and transverse elongated bosses29 forming intervening substantially serpentine nail receiving spaces orvoids and providing flaring entrances to the same for guiding a nailinto said spaces or voids. The ribs 28 extend from the outerlongitudinal edge of the flange on which they are formed and theyterminate short of the opposite longitudinal edge of said flange. Theribs 28 are provided at opposite sides with concave edges 30 and theirfront ends 2| are oppositely bevelled. The other ends 32 of the ribs 20extend to and terminate at the longitudinal edge of the flange of-theangle bar 21 and are preferablyflush with the same as shown and are ofgreater width than the bevelled ends 3|.

The bosses 29 are located between the concave side edges of the ribs andare oppositely tapered and present convex side edges 33 which are spacedfrom and arranged in substantial parallelism with the concave side edgesof the ribs and terminate short of the ends of the ribs to 'form withthe ribs substantially serpentine nail receiving pas- 10 sages or voids.The tapered ends 3| of the ribs are bevelled to a relatively sharp edgefor guiding nails or other fastenings into the serpentine voids orspaces in a manner similar to the tapered ends of the ribs heretoforedescribed.

In Figs. 13' and 14 of the drawings is illustrated another form of theinvention in which the protuberances which form serpentine nail re-'ceiving passages or voids are formed on one of the angles of an anglebar'34 consist of .rows Q 20 and 36 of circular bosses and amarginal orflanking row of tapered bosses 31. The circular bosses. of the rows 35and 36 are staggered with relation to one another, the circular bossesof each 'of the rows 35 and 36 being located opposite the in- 25 tervalsbetween the bosses of the other row. The tapered bosses 31 are locatedopposite the intervals betweenthe bosses of the row 35 and have roundedsubstantially semi-circular inner ends- 38 and bevelled outer ends 39presenting 0 straightinwardly diverging side edges 40 which extend fromthe front edge'of the bosses 31 to the curved edge of the inner end 38.The bosses 35- and 36'form substantially serpentine spaces or voidsbetween them for receiving and bending nails and other fastenings andthe tapered bosses 31 form guiding means for guiding nails or otherfastenings into the serpentine spaces or voids in a' manner similar tothe tapered bevelled ends of the ribs heretofore described.
